Rationalizing the Denominator Radical expressions, at times, are easier to work with if the denominator does not contain a radical. The process to clear the denominator of all radical is referred to as rationalizing the denominator 7.5 – Rationalizing the Denominator of Radicals Expressions

10
If the denominator contains a radical and it is not a monomial term, then the use of a conjugate is required. Review: (x + 3)(x – 3) x 2 – 3x + 3x – 9x 2 – 9 (x + 7)(x – 7) x 2 – 7x + 7x – 49x 2 – 49

Radical Equations: The Squaring Property of Equality: Examples: 7.6 – Radical Equations and Problem Solving

15
Suggested Guidelines: 1) Isolate the radical to one side of the equation. 2) Square both sides of the equation. 3) Simplify both sides of the equation. 4) Solve for the variable. 5) Check all solutions in the original equation. 7.6 – Radical Equations and Problem Solving
